I'm finding this question a bit difficult

Let $\displaystyle s_n$ denote the $\displaystyle n$th partial sum of the series:

$\displaystyle 1+\frac{1}{\sqrt{2}}+\frac{1}{\sqrt{3}}+...$

1) Show that $\displaystyle s_n>\sqrt{n}$ whenever $\displaystyle n>1$

2) Hence explain why the series diverges.

All I notice from this is that the series is:

$\displaystyle \sum_{n=1}^{\infty} \frac{1}{\sqrt{n}}$

And that this is a p-series which must obviously diverge
